Title: Variable passage width disc type mhd generator
Inventor: SHIODA SUSUMU
IPC: H02K44/08
Filed: 1988-05-02
Abstract: PURPOSE:To make the sampling rate of enthalpy constant by regulating the distance between sidewalls for a working fluid to pass through at the time of variation of the flow of the working fluid through variation of an electric power demand. CONSTITUTION:A variable passage width disc type MHD generator is composed of disc sidewalls 1, 2. The inflow working fluid 3 of the generator flows from a nozzle part 4 provided in the center of one sidewall 1 into MHD generator, is accelerated in a throat part 5 provided between the sidewall and the other sidewall 2 and then flows radially, passes through a generator part between an annular anode 6 provided on the small diameter side and an annular cathode 7 provided on the large diameter side, and passes through a diffuser part 8 and as an outflow working fluid 9 outward of the generator. Further, because the flow rate of the working fluid 3 is required to increase at the time of increase of an external load, the sidewalls 1, 2 are moved to vary the distance 10 so that it is proportioned to the increase. Thus, it is possible to regulate the cross section of a passage including the throat part 5.

Title: Reference voltage generating circuit
Inventor: HORIGUCHI SHINJI
IPC: G11C11/407
Filed: 1990-04-25
Abstract: PURPOSE:To generate a stable reference voltage whose external power supply voltage dependency is reduced by providing the reference voltage generating circuit with plural current mirror means for respectively suppling the 1st current proportional to a stabilized current to the 1st FETs and the 2nd current propor tional to the stabilized current to the 2nd FETs. CONSTITUTION:The reference voltage generating circuit is provided with a circuit for generating a stable current I whose variation due to an external power supply voltage Vcc is reduced and current mirror means M3, M1 allowing currents respectively proportional to the current I to the reference MOSFETs M1, M2. Since the current I whose variation due to the voltage Vcc is reduced is generated and the currents respectively proportional to the I are allowed to flow into the MOSFETs M1, M2 the ratio of currents flowing into the M1, M2 and the absolute values of the current values can be almost fixed. Thereby even when a characteristic difference exists between the M1 and M2, the varia tion of a VR due to the Vcc can be reduced. Consequently, the stable reference voltage whose external power supply voltage dependency is reduced can be formed.

Title: Optical ring network
Inventor: TAKEYARI RIYOUJI
IPC: H04L12/42
Filed: 1990-04-25
Abstract: PURPOSE:To improve the utilizing efficiency of a wavelength by allocating a line on the occurrence of service in a ring network so that an address is circulated through the ring in a same wavelength through a same fiber identified physically. CONSTITUTION:When a new line is set from a node 1-1 to a node 1-2, an idle line is searched by scanning a line control receiver. When an idle line is found out, a variable optical switch is selected and a line setting serial number is sent in a predetermined format and it is monitored by a receiver. Other nodes monitor a power of each line and discriminate whether or not the number is addressed to its own node. An address is sent to other nodes according to a similar format. In this case, the line setting serial number is used in common. The node 1-1 recognizes the establishment of the line by detecting the same line setting serial number. Thus, the line assignment and network control are facilitated because the logical line and the physical line correspond to each other one by one.

Abstract: PROBLEM TO BE SOLVED: To easily apply optimum transfer voltage in a short time by changing the value of the transfer voltage according to the value of a current flowing in a conductive member coming in contact with a transfer roller and applying the optimum transfer voltage to the transfer roller. SOLUTION: The transfer voltage having reverse polarity to the polarity of toner 7 is applied to a metallic shaft in the center of the transfer roller 25 from a high voltage power source for transfer 27 so as to transfer a toner image on an intermediate transfer body 16 to printing paper 20. In a state where the roller 25 is separated from the transfer body 16, the conductive member 31 is brought into contact with the roller 25 so as to apply the transfer voltage to the roller 25 by the power source 27. At such a time, the current flowing to the member 31 is measured by a current measuring device 32 and the resistance value of the roller 25 is measured from the relation between the transfer voltage applied to the roller 25 and the current flowing to the member 31.  When the current flowing to the member 31 is low, as the result of the measurement, the transfer voltage is made high, on the contrary, when the current flowing to the member 31 is high, the transfer voltage is made low.
